CLAMP FOR- BATTERY CONNECTIONS.

' Application filed May 5,

To all whom it may concern:

Be it known that we, FREDERICK Monm- SON and Former MAYs, citizens of the United States, residing at Huntington, in the county of Cabell and State of West Virginia, have invented certain new and useful Improvements in Clamps for Battery Connections, of which the following is a specification, reference .being had to the accompanying drawings.

This invention relates to battery clips or clamps by which a wire may be attached to the terminal or post of the battery.

The general object of the invention is to provide a clamp of this character by which the wire may be connected readily to the post or disconnected therefrom, and which is so constructed that a good electrical'conof the clamp nection will be made with the battery post.

A further object is to provide a. clamp of this character which is very simple, which may be quickl applied and qu ckly removed, and w ich may be cheaply constructed.

Other objects will appear in the course of the following description.

Our invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of our battery clamp in use;

Figure 2 is a longitudinal sectional view closed;

Fi re 3 1s a like view to Figure 2 but showing the clamp opened.

Referring to these drawings, it will be seen that our improved clamp comprises two opposed members 10 and 11. The member 10 at its middle is formed with a lug 12 which is reduced in thickness and the member 11 at its middle is formed with the two cars 13 which are ada ted to embrace the lug and receive throu them a pivot pin or bolt 14 whereby t e two members are pivotally connected to each other. The members 10 and 11 are formed at one end with the complementary or opposed jaws 15-. The member 10 is extended rearward beyond its pivot 14, east 16, and this rearwardly extending portion on its inner face is longttudinal-ly recessed, as at 17, the end of t is portion 16 having a recess 18 intersecting the recess 17 The member 11 upon its inner 1923.

tubular socket 20 for the reception of the cable or conductor 21. The extended portion of the member ll may be split longitudinally and then folded over and clamped down upon the cable or any other suitable I means may be used to electrically connect the bared end of the cable into the socket 20.

Coacting with the members 10 and 11 and operating within the recesses 17 and 19 is a cam 22 having a handle 23.. When this cam is inserted between the recesses 17 and 19 and the handle isturned into parallelism with the rear end of the member 11, the

cam will act to force the rear end of the member 10 outward and the opposed jaws 15 against each other. It will be seen that the cam is so formed that when the handle 23 is turned down into parallelism to the shank of the member 11 that the eccentric will have turned slightly t the center so that the cam will be hel in this osition until it is forcibly moved back. It as'not been found necessary to pivot this cam' to one or the other of the members 10 or 11,

a post 24 and the cam is in the sition shown in Figure 2, the cam cannot withdrawn. By turning the handle 23 outward so that it passes into the slot 18, the jaws may be opened so as to readily remove the clamp from the battery ost.

We do not wish to be imited to any par ticular manner of forming these elements 10 and 11. Preferably these members will be made of cop r so asto secure good con-- duction and a t orough electrical connection between the cable 21 and the post 24.

We claim g 1. A battery connector clamp of the character described comprising two opposed members pivoted to each other, each 0 said members being formed at one end with a jaw, the jaws confronting each other, one of said members extending beyond the pivotal point and being formed toembrace a cable and both of said members having longitudinally extending confronting recesses, and a cam disposed 'insaid recesses and havin handle is s ifted into a position parallel to one of saidlmembers, acting to force the jaws together and when shifted in the opposite'gdirection permitting the jaws to be open v v .2. A battery connector clamp of the chap acter described comprising two opposed for so long as the jaws 15 are clamped upon a handle, said cam, when the 3 members ivoted to each other, the members on one si e of the pivot being formed with i confronting jaws and said members extending beyon the pivot at the ends opposite said jaws, both 0 said members having confronting recesses rearward of the pivot and one of said members being extended beyond its recess and formed to provide a socket torecewe an electrlc connector, and a cam opened.

3. A battery clamp of the character described comprising complementary members having pivotal engagement with each other a handle, said cam when turned in between their ends, said members on one side of the pivot being formed with conironting jaws and the inner faces of said members rearward of the pivot being formed with confronting recesses, the recess in one member intersecting a recess extending inward from the outer edge of the member, the other member having its rear end longitudinally extended and formed to provide a split socket to receive a cable connector, and a cam disposed within said recesses and adapted when shifted in one direction to force the rear ends of the members apart and their jaw ends together and in the other direction to permit the jaws to open, said cam having a handle.

In testimony whereof we hereunto afiix our signatures.
